just booked for the first time. How do i find the address of where my dog shd be dropped off?

When the booking is confirmed, meaning the sitter has formally accepted it, then you will be prompted to finalize it on Rover. At that point, you would receive all the pertinent information.

However, I encourage you to have a Meet & Greet with the sitter to see where your dog will stay and discuss the engagement with the sitter. You can message sitter(s) to arrange these types of meetings and they will give you their address.
